      Hi Forum

      I'm trying to embed a swf movie using the mediaOutput (as described in the demo). But I can't get it to work.. It just happens nothing.

      I added the request scope beans MediaBean and MediaData.

      This my page:

      The Beans: 
      package com.antavis.groupware.handler;

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import javax.imageio.ImageIO;

public class MediaBean {

 public MediaBean(){

 System.out.println("*** DEBUG MEDIA BEAN INITIATED...");
 }

 public void paint(OutputStream out, Object data) throws IOException{
 if (data instanceof MediaData) {

 MediaData paintData = (MediaData) data;
 BufferedImage img = new BufferedImage(paintData.getWidth(),paintData.getHeight(),BufferedImage.TYPE_INT_RGB);
 Graphics2D graphics2D = img.createGraphics();
 graphics2D.setBackground(paintData.getBackground());
 graphics2D.setColor(paintData.getDrawColor());
 graphics2D.clearRect(0,0,paintData.getWidth(),paintData.getHeight());
 graphics2D.drawLine(5,5,paintData.getWidth()-5,paintData.getHeight()-5);
 graphics2D.drawChars(new String("RichFaces").toCharArray(),0,9,40,15);
 graphics2D.drawChars(new String("mediaOutput").toCharArray(),0,11,5,45);

 ImageIO.write(img,"jpeg",out);

 }
 }

 private void copy(InputStream in, OutputStream out) throws IOException {
 byte[] buffer = new byte[2048];
 int read;

 while ((read = in.read(buffer)) != -1) {
 out.write(buffer, 0, read);
 }
 }

 public void paintFlash(OutputStream out, Object data) throws IOException {
 ClassLoader loader = Thread.currentThread().getContextClassLoader();
 if (loader == null) {
 loader = getClass().getClassLoader();
 }

 InputStream stream = this.getClass().getClassLoader().getResourceAsStream("../../scripts/create_time_report.swf");
 if (stream != null) {
 try {
 copy(stream, out);
 } finally {
 stream.close();
 }
 }
 else{
 System.out.println("*** DEBUG MOVIE - STREAM NULL...");
 }
 }
}


      
package com.antavis.groupware.handler;

import java.awt.Color;
import java.io.Serializable;

public class MediaData implements Serializable{

 private static final long serialVersionUID = 1L;
 Integer Width=110;
 Integer Height=50;
 Color Background=new Color(0,0,0);
 Color DrawColor=new Color(255,255,255);
 public MediaData() {
 }
 public Color getBackground() {
 return Background;
 }
 public void setBackground(Color background) {
 Background = background;
 }
 public Color getDrawColor() {
 return DrawColor;
 }
 public void setDrawColor(Color drawColor) {
 DrawColor = drawColor;
 }
 public Integer getHeight() {
 return Height;
 }
 public void setHeight(Integer height) {
 Height = height;
 }
 public Integer getWidth() {
 return Width;
 }
 public void setWidth(Integer width) {
 Width = width;
 }
}


      It seems like the MediaBean class is never initiated.. What am I doing wrong?
      Thank you very much for a hint!
      Best regards
      Alan
